EBS - change connection to another db

[mape]

Hi

I would like to know some important informations what I try to find out.
And if you gimme some notes I would a really appreciate it from you.

I have EBS 12.1.3. and I need to change communication into another one database.
This database is 12.1.0.2.0 runs on Linux x86.

What I have to do to change database?
Is it enough to make changes just in the current context_file?
 

I tried to change db name on context_file and but autoconfig does not end without errors.

You just cant switch EBS databases like that. Ebs has its own schema model.

You just cant do such an operation by just modifying the context file.

Also ebs should have a dedicated database. You cant just share  databases of other applications with EBS.

İf you want to use 12c database with your Ebs 12.1.3 ; i suggest you to  follow the Ebs specific database upgrade docs and upgrade your EBS database  to 12c.

The new database was migrated from 11g Enterprise Edition Release 11.2.0.2.0 to Oracle Database 12c Enterprise Edition Release 12.1.0.2.0.  on Linux x86.

Till now EBS 12.1.3 uses database 11g (Unix).
Now EBS 12.1.3 is still runs on Unix on one machine and the new database 12c runs on another machine (Linux). All I just need to figure out is how to tell EBS to use the new database.
I dont know if you get it what I mean.

you can't just migrate EBS database from 11g to 12c, like you migrate other oracle databases .
EBS and 12c have to be interoperable. There are a lot of tasks need to  be done to accomplish that.

You question ( All I just need to figure out is how to tell EBS to use the new database) is unnecessary. It will not work even if you do a post clone to make your EBS application tier use that db.

I think your EBS is down right now right?

This is not the way. You need to apply patches to EBS to make it interoperable with 12c, then migrate your database tier to 12c using a supported method (with all the schemas and data) and clean the fnd_tables and run autoconfig in the database tier, then you  need a post clone to tell the EBS apps tier to use the newly migrated 12c db.

check this one and you ll understand what I mean.
